The Lowdown
Alright, let's get real about Kennebunk Beach for the next couple of weeks. It's looking like a long stretch of small, choppy, and generally disappointing waves. Almost every day is a struggle with onshore wind and tiny swell. The first real sign of life doesn't show up until the 5th of September.
Wednesday 26th August starts us off with a tiny 2ft SE swell. A cross-on breeze from the SSE at 6 mph keeps things bumpy. The wave energy is super weak (67). You'd be better off taking a nap. Thursday the 27th brings a storm risk and a 5ft swell, but it's a short-period 5-second thing, blown out by a 12 mph S wind. That's a messy, closed-out mess. Not for paddling.
The pattern stays poor. We get a clean, glassy moment on the Saturday 29th morning with a light ENE breeze, but the swell is only 2ft. It's clean but has no power. Through the end of August and into September, we get a few cleaner days with offshore winds from the NE. Wednesday 2nd September morning has 2ft SE swell and a light 6 mph offshore. It's clean as a whistle but the energy is just 87. A longboard might get a slide, but that's it.
Finally, something changes on Saturday 5th September. We see a 3ft E swell with an 8-second period. The wind is a clean cross-off from the ENE at 9 mph. The wave energy jumps to a moderate 144. The surf will be rideable, but it's nothing to write home about. Still, it's the best we've seen. The water temp is about average for this time of year.
The Sunday 6th gets messy again with onshore wind until we hit the real gem: Thursday 10th September morning. The wind goes glassy from the NE at 3 mph, and we get a 4ft E swell. The wave energy is a solid 149. This is the cleanest, most substantial window of the whole forecast. It'll be a fun longboard day. The break is sometimes crowded, so don't expect to have it to yourself.
Bottom line: The first week is a total loss. The only session worth chasing in this whole 16-day run is that Thursday 10th September morning. Mark it on the calendar.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
